Compact Size: The ATtiny85 is much smaller than typical Arduino boards, making it ideal for projects where space is a constraint.
USB Interface: The USB connection allows for easy programming and power supply. This is particularly useful for beginners and those looking to streamline their development process.
Arduino IDE Compatibility: The ATtiny85 can be programmed using the familiar Arduino IDE, which simplifies the coding process. This compatibility extends to various libraries and functions available in the Arduino ecosystem.
I/O Pins: It has 6 I/O pins, which can be configured for digital input/output, analog input, PWM output, and more.
Memory: It comes with 8KB of flash memory, 512 bytes of SRAM, and 512 bytes of EEPROM, providing ample space for small to medium-sized projects.
